A New Secure Data Forwarding Protocol with Fault Detection for Wireless Ad Hoc Networks

In wireless ad hoc networks, the route discovery process or the data forwarding process is vulnerable to attackers. In this paper, we address the data forwarding security problem and propose a light-weight secure data forwarding protocol, which utilizes one-way hash chains to achieve the message integrity, where the intermediate nodes can effectively detect the fault link and the source node of the packet can correctly judge whether the peer-to-peer data transfer is successful.
